7. DISCUSSION and BACKGROUND
The City Council awarded the Cambridge Storm Drain Project on May 8, 2018, to Garrett J
Gentry Engineering. Due to an unforeseen utility conflict with an AT&T utility duct bank, the
project plans were modified to accommodate and protect the AT&T facility in place. This
unexpected change to our storm drain alignment has resulted in a loss of production and
additional work costs.
The staff has contacted AT&T regarding the utility conflict and has asked that they reimburse the
City for this extra cost to protect the AT&T facility in place. The City sent AT&T utility
notifications prior to the start of the project and they did not indicate any conflict with the City's
proposed storm drain alignment. AT&T's actual facility location in the field is different from
what was shown on the utility map, so the City's extra cost incurred by revising the construction
plan and change order should be reimbursed by AT&T per the franchise agreement.
The original contract amount was $1,064,925. This Contract Change Order represents a 10.29%
increase from the original contract amount bringing the final contract amount to $1,174,506.

This letter is to notify you of the loss of production and the costs incurred caused by AXI s mismarked duct bank being in our way.
We originally bid this project at a production rate of 100' LF per day pulling a shield. Due to This duct bank being located one foot
inside the pipe zone.of proposed 72" RCP Storm Drain there is not enough room to utilize a shield. Therefore, hydraulic shoring must
now be used slowing our production rate to approximately 32' LF per day. In addition ... the existing manhole bases are also in conflict
with the proposed storm drain causing the need for additional manholes to be built. The cost incurred are reflected on Change Order
